Lenovo E40-30 Power Adapter
If you decide to buy an non-Lenovo adapter, please check on the output of amps and voltage. Due to the fact that one Lenovo adapter powers multiple other machines, double-check the part number or model number of the adapter. The Lenovo E40-30 power adapter provides two functions, to charge any and all batteries and powering the laptop. A universal power adapter is another possibility if you absolutely need to. When choosing a new AC adapter, choosing the Lenovo brand one is the best one to choose.
Signs of a faulty AC adapter
- The majority of Lenovo power chargers will get very warm to the touch when plugged in for 10 minutes or more
- The laptop does not work without the battery installed
- Your Lenovo battery refuses to charge up completely
